\YILLIAM MCGREGOR, OF APPLETON, WISCONSIN, ASSIGNOR TO THE APPLE- TON MANUFACTURING COMPANY, OF SAME PLACE.

FOUR-HORSE EVEN ER.

SPECIFICATION forming part of Letters Patent No. 414,433, dated November 5, 1889.

Application filed January 16, 1889. Serial No. 296,539. (No model.)

To all whom it may concern:

Be it known that I, XVILLIAM MCGREGOR, of Appleton, Wisconsin, have invented certain new and useful Improvements in Four- Horse Eveners, of which the following is a specification.

My invention relates particularly to evene'z-bars for four-horse barrows, and my object is to provide an evener which shall be light,

and yet so connected to the harrow and to the whifiietrees that it shall not spring or flex under the strain, and the attached harrowsections are kept in line.

The accompanying drawing is a plan view of a barrow composed of five sections 0011- nected to an evener of my improved construction.

In said drawing, A represents an evenerbar, to which the barrow-sections are flexibly connected independently of each other, as at a.

B is a stiffening-bar secured edgewise along the front edge of bar A by means of the straps b;

0 represents a sheave-arm, which is bolted to the upper side of the bars A B, and it has a telly-arm bolted to their under sides. These arms are located at the middle of bar A, and between their projecting ends is journaled a sheave D. The whiflietrees E have draft-rods F, connected to the evener-bar A toward its outer ends, respectively, and draft-rods G, connected at one end to the Whiflietree and at the other to the chain H, which latter is passed under the sheave D. Thus it is apparent that each whiftletree draws from three points evener-bar can be used than in the common forms of construction, because of the fact that the strain is divided, and also because of the p additional strength imparted by the stiffenerbar.

I claim A 1. In an evener, the combination, with the main evener-bar,of a stiliener-bar secured to said evener-bar, and a sheave secured cen 5 5 trally of the said bars to form one of the draftconnections, substantially as described.

2. In an evener, the combination, with the evener-bar, of draft-rods whereby to connect the Whiftletrees to the outer ends of the bar,

and draft-rods connected to each other by a flexible section, and a sheave secured centrally of the bar, and under which said flexible section is passed.
